Specification of Letters Patent.

Patented July 13, 1920.

Application filed October 16, 1918. Serial No..258,324.

To all whom it may concern:

Be it known that I, GIUsnPrE VrrULLI MoNTARULI, a subject of the King of Italy, and residing at 29 via Brescia, Rome, Italy, have invented certain new and useful Improvements in the Construction of Ships, of which the following is a specification.

The object of this invention is to design and construct hulls of a new geometrical shape for ships of any type and for any traflic.

This new geometrical shape of the hull comprises at the center a cylindrical portion of almost elliptical cross section and tapered fore and aft end portions which extend onward from the terminal sections of the cylindrical portion along gradually narrowed or flute beak sections and end in a straight line section along the bow and the stern.

The essential feature of the invention is the geometrical shape of hulls constructed in accordance with this new method of ship construction and same is illustrated by way of example in the accompanying drawing, in which- Figure 1 shows on the left-hand side, in 1, the midship section of the hull and on the right-hand side, in 2, the curvature of this section,

Fig. 2 shows the hull divided into three parts 3, 4 and 5 of different geometrical shape,

Fig. 3 shows in horizontal position and Figs. 1 and 5 show in projections of vertical sections the shape of the hull forward and aft in accordance with the invention.

In Fig. 1, the curve portion ABC is a circular arc which has its center at D and connects at its ends A and C with other circular arcs AE and CF whose centers are respectively in G and H, so that these circular arcs set up the curve EABCF which consists of circular segments arranged to form half a section of the central part 3 on Fig. 2 of the hull. The hull will thus have at its center part a cylindrical shape of constant section.

The forward end 4 (Fig. 2) is built up from section 6 of midship section onward with the aid of sections 7 8, 9, 10 and 11 tapered below so as to leave there a free space for the working of the screws.

The shape of the hull built up in the above described manner allows its main parts being constructed with interchangeable elements of constant curvature, whereby a standardization of the construction is attained for building ships in series.

As regards the central cylindrical portion of the ship this construction is shown schematically in 1 on the left-hand side of Fig. 1. In this central partthe section of the hull consists substantially of a frame 20 which may have the section of any ordinary bar used in shipbuilding, and of layers of plates to form the outer plating 21.

A double bottom 22 may have any desired shape, and 23 is a hatchway and 24 a section of the deck in correspondence with the hatchways.

What I claim is:

A ship having a plurality of transverse frames, the frames for a determinate length of the ship being formed with side sections of constant curvature and top and bottom curved sectionsv having radii approximately twice the length of the radii of said side sections, the remaining portion of the ship having similar frames with straight porlength.

In testimony whereof I have signed my name in the presence of two subscribing witnesses the 21 day of August,-1918.
